Analysis and Simulation of Analogue Dynamic Compressors and Limiters in the Digital Domain

A method for applying nonlinear synthesis to analyze and simulate traditional audio dynamics compressors and limiters is described. A set of level-dependent impulse response measurements was taken at each of the multiple attenuation levels. In addition, a measurement of attenuation characteristic against applied signal amplitude was made at various settings of the device and applied in simulation, and a bilinear dynamic convolution was performed varying on a sample-by-sample basis.:
